Hi Andrew,

 

That patch does indeed fix it, thanks!

 

I should have mentioned that I was using base 7.0.6, and I didn’t realize I was using a new feature from 7.0.5, and I wasn’t too familiar with how the RELEASE files are parsed, but it makes sense now.

 

Cheers,

Matt

Although this causes errors like these when building asyn:

Oops! This patch to Base should fix the problem, please try it:

 

diff --git a/src/tools/EPICS/Release.pm b/src/tools/EPICS/Release.pm

index 7caa6f4c6..e6aaf1e0c 100644

--- a/src/tools/EPICS/Release.pm

             next;

         }

 

 



Do you know what's causing these errors? I suppose the script just isn't silently dealing with the 'undefine' syntax? 

 

Yup, and I evidently didn’t test the code properly when I added support for undefine (in Base 7.0.5 I believe).

 

Thanks,
